I have a MacBook Pro, running Snow Leopard and I'm using a Magic Mouse which connects through Bluetooth.

While I like the mouse, it's way too slow for my taste. Moving the mouse cursor takes ages. On my Windows PC I'm using a Logitech G9 and in Control Panel of Windows I have set Pointer Speed to maximum with the 'Enhance Pointer Precision' box checked.

On OS X I have set the speed set to maximum as well, but it's still way to slow. I'm used to move the pointer from from egde of the screen to another one with minimal wrist movement.

USB Overdrive is a popular program
that works with just about any USB or
Bluetooth input device. It allows
users to customize mouse acceleration,
scrolling, clicking, and more. You can
even configure per-application
settings. A new version that supports
Multi-Touch in Apple’s Magic Mouse is
in development and expected soon.

Aside from mouse acceleration,
SteerMouse offers a ton of other
advanced features. Configure up to 16
buttons, modify scroll wheels/balls,
and set the cursor to automatically
move to a specific location on the
screen when a window is activated.
Support for the Apple Magic Mouse is
pending.

While MouseZoom does not alter the
acceleration curve itself, it does let
users bump tracking speeds beyond
those available in System Preferences.
An ideal solution? No, but it’s a free
alternative that helps ease the pain.

This Preference Pane is based on
Richard Bentley’s MouseFix – a
non-user-friendly command line
utility. This version, however, makes
it easy to increase mouse precision
and speed up mouse movement with
visual aids.

This is a brand new piece of software
that just came to be within the past
couple weeks. It’s in beta and still
buggy, but it packs some nice features
and is in active development. I can’t
say for sure whether it customizes OS
X’s acceleration curve or just
supercharges the maximum tracking
speed. The real reason to give it a
shot, though, is if you have a Magic
Mouse or MacBook that supports
Multi-Touch gestures. BetterTouchTool
lets users assign specific actions to
advanced finger gestures and can
simulate a middle-click. It can even
bring the Mighty Mouse’s Exposé
functionality to the Magic Mouse.

ControllerMate is a controller
programming tool that allows you to
customize the behavior of your HID
devices — keyboards, keypads, mice,
trackballs, joysticks, gamepads,
throttles, among others.
ControllerMate’s philosophy is to be
as flexible as possible, to provide a
set of basic programming tools, and to
allow the user to combine those tools
in an endless variety of ways.
